Differential-wise, there's the OEM torsen (that might be the same unit that's in the ISF), an OS Giken, some other clutch type that I can't remember and whatever crappy viscous/open diff that comes in the vanilla IS.

Found this on the net on what diffs can fit the IS300. Also below is a list of the LSDs available. I guess OS Giken can be added. Also read that MkIII supra diffs fit. Gearing options from supras run from 3.27/3.13 to 4.27. Wonder what the FRS/BRZ rocks?
Differentials:
1. TT supra (93.5 - 98)
2. GS4's
3. Automatic Supra rear
4. MKIII 86-88 ?
LSD's
1. TRD
2. KAAZ
3.OS Giken
4. Torsen
5. Viscus
Really think for the $$$ if the gearing is not stupid crazy priced like powerhouse gearing is ($1300) coupled with a OS Giken you can have some serious fun.
